What is 3G2?

3GPP2 (3G2) is a multimedia container format developed for CDMA mobile networks, supporting video and audio streaming.

What is Y4M?

Y4M (video/x-raw-yuv) uses lossless compression optimized for lossless video processing, codec testing, video production intermediates. YUV4MPEG2, uncompressed YCbCr 4:2:0 video stream for encoding pipelines

When Should You Use 3G2 vs Y4M?

3G2 vs Y4M: Key Differences

• •3G2 and Y4M diverge on compression: lossy compression for the source, lossless compression for the target.
• •Moving from 3G2 (lossless) to Y4M (lossless) means the output file will be larger — but every bit of the original is preserved.
• •How transparency is handled: Y4M supports transparency, so alpha information is preserved during conversion.
• •Y4M files tend to be differently sized than 3G2
• •3G2 is optimized for legacy mobile video, mms messages while Y4M is designed for lossless video processing, codec testing, video production intermediates — choose based on your specific workflow needs

Advantages of 3G2

• ✓3G2 applies lossy compression specifically calibrated for Legacy mobile video, MMS messages.
• ✓3G2 enjoys broad native support across operating systems, browsers, and creative tools alike.
• ✓3G2 delivers impressive compression ratios, shrinking files dramatically while keeping visual quality high.
• ✓You will find 3G2 support built into virtually every tool that handles Legacy mobile video, MMS messages — no plugins or converters needed.

Advantages of Y4M

• ✓Y4M applies lossless compression specifically calibrated for Lossless video processing, codec testing, video production intermediates.
• ✓Y4M enjoys broad native support across operating systems, browsers, and creative tools alike.
• ✓Y4M guarantees every bit of the original data survives — no approximations, no shortcuts.
• ✓You will find Y4M support built into virtually every tool that handles Lossless video processing, codec testing, video production intermediates — no plugins or converters needed.

Troubleshooting 3G2 to Y4M Conversion

• !Video stutters during playback of Y4M → the frame rate may need adjustment; matching the source frame rate avoids judder
• !Black bars appear around the converted Y4M → check aspect ratio and cropping settings before re-encoding
• !Subtitles vanished after 3G2 to Y4M conversion → some containers handle subtitle tracks in separate streams
• !Y4M file won't upload to a streaming platform → verify the format, codec, and bitrate comply with the platform's specifications
